[0052] The present invention discloses a method and composition for protecting ear from waterborne ear canal disorders by using ear protection composition.
[0053]
[0054] Particularly, the device is an ear spray device useful in preventing common ear canal disorders caused due to trapping of water in the ear canal of the user.
[0055] In accordance with one or more embodiments of the present invention, the ear protection composition includes 99.9% w/v of a mineral oil and 0.1% w/v of a vegetable oil. Preferably, in various embodiments, the mineral oil is in the range of 98.0 percent w/v to about 99.9 percent w/v, and the vegetable oil is within the range of 2.0 percent w/v to 0.1 percent w/v.
[0056] Even more preferably, the mineral oil is about 99.9 percent w/v and the vegetable oil is about 0.1 percent w/v.
[0057] In particular embodiments, the mineral oil is Paraffinum Liquidum and vegetable oil is an Oreganum Oil.
[0058] The said liquid paraffin used in the said composition is an oily, transparent and colorless liquid obtained in the process of petroleum distillation. At room temperature it is odorless and tasteless although if heated it will exert a petroleum smell. Due to its chemical properties, it has many uses including industrial, medical as well as cosmetics.
[0059] Furthermore, due to its oily (emollient) properties and water resistance, the said liquid paraffin can coat skin surfaces and membranes to naturally repel and dissipate water, which makes it an essential ingredient in the composition to form a waterproof barrier in the ear canal. The other advantage is that it is not readily absorbed through the skin or mucous membranes into the body and is non-toxic.
[0060] Moreover, the said Orenagum Oil is an essential oil selected from at least one of the species of the Oreganum family an Oreganum Compactum, an Oreganum Vulgare, a combination thereof.
[0061] The said oregano oil is usually derived from the leaves and flowers of Oregano (Origanum Vulgare), a hardy perennial herb, and a member of the mint (Lamiaceae) family. The oil contains compounds called phenols, terpenes and terpenoids which are known to have powerful antioxidant properties and are responsible for its distinctive fragrance. Some of the key components of the said oil are as follows: [0062] Carvacrolthis is the most abundant phenol in oregano oil, and it has been shown to inhibit the growth of several types of bacteria. [0063] Thymolthis is known to be a natural antifungal compound and can also support the immune system and protect against toxins. [0064] Rosmarinic acidthis is known to be a powerful antioxidant that helps protect against damage caused by free radicals.
[0065] The said composition of the present invention forms a thin water repellent layer topically to an external ear canal of the user. Also, Orenagum Oil is an antimicrobial agent, a natural antibacterial agent, an antifungal agent and an antiseptic agent effective against a plurality of bacteria, a plurality of fungi, a plurality of viruses and microbes responsible for problems of said ear canal.
[0066] In accordance with another embodiment of the present invention, the method for preventing ear canal disorders and/or ear problems includes applying the ear protection composition in a metered dose in the ear canal before entering into water. Preferably, the said metered dosage of the ear protection composition is 0.1 ml to 1.0 ml. However, it should be understood that such dosage volume should not be considered as a limitation of the present invention.
[0067] Particularly, as described above, the composition has a combination of oils selected from a water repellent agent and an antimicrobial agent. Moreover, the water repellent agent is Paraffinum Liquidum having 90.00% w/v to 99.75% w/v and antimicrobial agent is Orenagum Oil having 0.25% w/v to 10% w/v. Subsequently, the ear protection composition forms a thin water repellent layer topically to an external ear canal of a user.
[0068] In accordance with yet another embodiment of the present invention, the present invention further discloses an ear spray device dispensing a pre-defined quantity of the ear spray to the ear canal of the user. Particularly, referring to
[0069] In particular, the ear protection composition includes a combination of oils selected from water repellent agent and antimicrobial agent, according to various embodiments described hereinabove.
[0070] Moreover, the spray nozzle (108) is adapted to spray the combination of oils inside the ear canal of the user when the ear spray device is in either a substantially upright or a substantially inverted position.
[0071] The pump mechanism as provided herein includes a pipette (114) enclosed in a housing (100). The said pipette (114) extends into the said reservoir (115), wherein the said ear protection composition is stored.
[0072] Further, the said pump mechanism also includes a spring (102), a secondary piston (103), a piston (104), a collar (105), a gasket (106), an actuator (110), and a closure (107) adapted to close the opening mouth of the said reservoir (115).
[0073] In various embodiments, the spring (102), the secondary piston (103), the piston (104), the collar (105), the gasket (106), the actuator (110), and a closure (107) are arranged to form the pump mechanism and are covered by the dust cap (113).
[0074] Further, a rod (112) and a rotating block (111) operatively couples the pump mechanism with the spray nozzle (108) in such a form that the said ear protection composition is applied inside the ear canal when the said ear spray is in a substantially upright or a substantially inverted position.
[0075] As such, the pump mechanism operatively couples the reservoir (115) with the spray nozzle (108) and is adapted to draw the combination of oils from the reservoir (115) spraying the combination of oils via the spray nozzle (108) inside the ear canal of the user.
[0076] As described hereinabove, the combination of oils includes 99.9% w/v of Paraffinum Liquidum and 0.1% w/v of Oreganum Oil forming thin water repellent layer inside the ear canal of the user.

Discussion on Biological Safety of the Composition
1. Biological Safety Evaluation (Safety of Liquid Paraffin)
[0080] Paraffinum Liquidum is a mixture of hydrocarbons having the general formula C.sub.nH.sub.n and is obtained from petroleum oil before being highly refined to a very pure form using filtration and acid treatment. Paraffinum Liquidum is an odorless and tasteless, translucent, and colorless. Paraffin is stable and should be stored below 40 C. in a well closed container.
[0081] Paraffinum Liquidum is generally regarded as an essentially nontoxic and non-irritant material when used in topical ointments and as a coating for tablets and capsules. However, granulomatous reactions may occur following injection of paraffin into tissue for cosmetic purposes or to relieve pain. Long-term inhalation of aerosolized paraffin may lead to interstitial pulmonary disease. Ingestion of a substantial amount of white soft paraffin is known to cause intestinal obstruction.
2. Safety of Oregano Oil
[0082] Oregano oil is known to be an irritant rather than an allergen, and a topical maximum has been set at 1.1% after which irritation can occur in some people. An adverse skin reaction study using undiluted oregano oil was severely irritating to mice, and moderately irritating to rabbits. In usual tests, the said oil tested at 2% on 25 volunteers it was neither irritating nor sensitizing. Oregano oil is non-phototoxic.
[0083] In a CAM (chorioallantoic membrane of the fertile chicken egg) assay, a model for detecting irritants, Origanum Onites Oil with 57.4% carvacrol and 11.6% thymol is strongly irritating. The level of Oregano Oil incorporated in the formulation is well below that noted to cause irritation or adverse skin reactions.
Cardiovascular Effects
[0084] Origanum Vulgare oil inhibits platelet aggregation, an essential step in the blood clotting cascade.
Reproductive Toxicity
[0085] When Origanum Vulgare oil was fed to pregnant mice for two weeks at 1,000 ppm (equivalent to 150 mg/kg), studies show there was a related increase in the rate of embryonic cell death.
Genotoxicity
[0086] Another study investigated the use of micronucleus and comet assay to evaluate the genotoxicity of oregano oil in rats orally exposed for 90 days. The results obtained in the genotoxicity assays indicated lack of effect in MN and standard comet assay under the conditions tested. Furthermore, no apparent oxidative damage was observed in the enzyme-modified comet assay in any of the tissues examined of rats exposed to oregano essential oil for 90 days. Therefore, this oregano essential oil appears to be safe in Wistar rats.
Oral Toxicity
[0087] A subchornic 90-day oral toxicity study of Oregano oil was conducted in rats. Data revealed no mortality and no treatment-related adverse effects of the OEO in food/water consumption, body weight, haematology, biochemistry, necropsy, organ weight and histopathology. These findings suggest that the oral no-observed-adverse-effect level (NOAEL) of this OEO is 200 mg/kg bw in Wistar rats, the highest dose tested. In conclusion, the use of this OEO in food packaging appears to be safe based on the lack of toxicity during the sub-chronic study at doses 330-fold higher than those expected to be in contact consumers in the worst scenario of exposure.
